Any Solution to: An error has occurred in the script on this page ???

I search the world over for a solution to an error that I get every time I load the date select calendar. The search has been fruitless. The error I get is: An error has occurred in the script on this page. ??? It refers to a prompting1.html (several directories deep).

Can anyone help me resolve this issue. None of the solution I tried from the web seem to work.

Thank you in advance.
